i meet the same problem as qwerty753 posted in 2009.
Boundary condition for Porous media in NLTE
NLTE model for porous media flow, first i use a UDS to compute solid equation.
Now i have a question about BC? I should apply this one on a wall.
how can i define this boundary, this boundary condition is seen from many papers about tube and channel filled with porous!
on the same wall...
q_tot is tube wall flux, q_fluid and q_solid are the fluid and porous media flux at the wall, the both are get from the iteration. Tf and Ts are unknown, are the temperature at the wall.
So if i apply the two fluxes on two domains Tf will different from Ts and it's a problem
Can you help me? can use UDF or....
